The House of Bourbon, descendents of the French Capetian dynasty, can be dated back to the Count Robert de Clermont (1256-1317), the sixth son of King Louis IX, and his descendents, the Dukes de Bourbon. France's last eight kings, from Henri IV (reign 1589-1610) to Louis-Philippe  (reign 1830-1848) and perhaps the most powerful and famous of them all, Louis XIV, the Sun King (reign 1643-1715) were of Bourbon blood.
One of Louis' sons, Philippe d'Anjou, became King Felipe V of Spain in 1700.
Either directly, or through various branches (Bourbon Orléans, Bourbon Two Sicilies, Bourbon Parma, Orleans-Braganza)  the Bourbon family  is linked to most European Royal families.
